critical Nessus Plugin ID 210202

Synopsis

The remote Red Hat host is missing a security update for Red Hat OpenStack Platform director.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:1242 advisory.

Red Hat OpenStack Platform director provides the facilities for deploying and monitoring a private or public infrastructure-as-a-service (IaaS) cloud based on Red Hat OpenStack Platform.

Security Fix(es):

* A design flaw issue was found in the Red Hat OpenStack Platform director use of TripleO to enable libvirtd based live-migration. Libvirtd is deployed by default (by director) listening on 0.0.0.0 (all interfaces) with no-authentication or encryption. Anyone able to make a TCP connection to any compute host IP address, including 127.0.0.1, other loopback interface addresses, or in some cases possibly addresses that have been exposed beyond the management interface, could use this to open a virsh session to the libvirtd instance and gain control of virtual machine instances or possibly take over the host.
